| 摘 要： | 1997年在柴达木盆地东部（柴东地区）五道梁及北霍布逊湖地区发现了两片共7处航放异常。本从基础地质条件出发，分析、研究了柴东地区的区域地下水动力条件，对航放异常区的放射性水地球化学特征进行了分析，重点解剖了五道梁地区航放异常。从水地质角度探讨了航放异常成因，认为其反映了深部铀成矿信息，进而指出柴东地区有利于形成层间氧化带砂岩型铀矿化，值得进一步工作。

| Abstract: | Two anomalous areas composed of seven airborne radioactive anomalies were discovered in Wudaoliang and north Huobuxun lake, eastern Chaidamu basin in 1997.Based on basic geological conditions, and using the theory of groundwater system, this paper presents dynamic conditions of regional groundwater in eas tern Chaidamu basin. Meanwhile, radioactive hydrogeochemical characteristics in airborne radioactive anomalous areas are analyzed, and airborne radioactive anomalies in Wudaoliang area are emphatically discussed. From the aspect of hydrogeology the genesis of airborne radioactive anomalies is suggested and those anomalies can be considered as the information of deep uranium mineralization. Furthermore, the author suggests that the eastern Chaidamu area is favorable for the formation of interlayer oxidation zone sandstone type uranium mineralization, and is worth further prospecting. |
